@sofy     after I let it load for a very long time it went to a 503 screen and in console it said 

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'debug')
at content-scope-messaging.js:32:29Understand this error

When I click content-scope-messaging.js 

const allowedMessages = [
    'getClickToLoadState',
    'getYouTubeVideoDetails',
    'openShareFeedbackPage',
    'addDebugFlag',
    'setYoutubePreviewsEnabled',

    'updateYouTubeCTLAddedFlag',
    'updateFacebookCTLBreakageFlags'
